2013-02-12ASoC: arizona: Automatically manage input mutesMark Brown
For optimal performance the inputs should be kept muted until after power up. Since there are few use cases for muting inputs during capture move the mutes to automatic control. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-02-07ASoC: arizona: Fix debug logging level for FLLs and AIFsMark Brown
Use _dbg for debug messages. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-02-04ASoC: arizona: Fixed a bug in FLL fractional calculationRyo Tsutsui
Previously arizona_calc_fll() was checking if the target frequency is exactly divisible by reference frequency, but should have been product of the ratio and the reference frequency. Also scale down the Lamba and Theta coefficients be under 16-bits in order to match the registers.

2013-01-21ASoC: arizona: Allow number of channels clocked to be restrictedMark Brown
Place a cap on the number of channels clocks are generated for. This is intended for use with systems which have the WM5102 master an I2S bus with multiple data lines. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-21ASoC: arizona: Support clearing clocksMark Brown
Some systems may wish to support switching between telephony and CD audio clock rates but this is restricted by enforcement of constraints on the current DAI clock. Support setting clocks to zero and don't enforce any constraints in that case in order to facilitate this use case. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-01-17ASoC: arizona: Use actual rather than desired BCLK when calculating LRCLKMark Brown
Otherwise we'll get the wrong LRCLK if we need to pick a higher BCLK than is required. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@vger.kernel.org
2013-01-16ASoC: arizona: Don't request FLL lock IRQMark Brown
We only log the result and since the interrupt triggers on loss of lock during shutdown this may lead to spurious interrupts during shutdown delaying the process. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-01-08ASoC: arizona: Disable free-running mode on FLL1Charles Keepax
The free running mode can cause problems when attempting to bring up the FLL running from a defined clock source. This patch disables free-running mode. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-04ASoC: arizona: Factor out rate selection codeMark Brown

2013-01-04ASoC: arizona: Allow runtime reconfiguration of the output modeMark Brown
Some systems use external analogue switches to connect more analogue devices to the CODEC than are supported by the device. In some systems this requires changing the switched output from single ended to differential mode dynamically at runtime. Add a new function arizona_set_output_mode() to support this.

2012-12-24ASoC: arizona: Do proper shift for setting AIF rateAxel Lin
ARIZONA_AIF1_RATE_MASK is 0x7800 /* AIF1_RATE - [14:11] */ Thus we need left shift ARIZONA_AIF1_RATE_SHIFT when setting aif1 rate. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@vger.kernel.org

2012-12-06ASoC: arizona: Make FLL lock timeout very highMark Brown
Provide robustness against low quality FLL sync clocks by increasing the timeout for lock to an absurdly high point; we should never get anywhere near hitting the timeout in a real system unless it is failing. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-08-09ASoC: arizona: Implement OPCLK supportMark Brown
Arizona devices support two output system clocks. Provide support for configuring these via set_sysclk(). Once the clock API is more useful we should migrate over to that. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-07-04ASoC: arizona: Be more forgiving in BCLK selectionMark Brown
